B. How to cause cancer of nitrite
Nitrite is a strong carcinogen that can be converted into nitrosamine, and then reacts with ammonia and other substances to generate carcinogens.After entering the human body, nitrite can be converted into nitrosamines under the action of gastric acid, and then reacts with the protein in the stomach to form nitrosamine.These substances can be combined with macromolecules such as DNA, leading to changes in gene mutations and apoptosis, increasing the risk of cancer.
